This invention relates to conveyer chains for the distributing or restoring device for the patrices of type setting machines such as type line composing and casting machines or type line composing and printing machines or the like wherein patrices or the like provided with control portions for restoring the same are conveyed along a restoring rail to be admitted to the maga- Conveyer chains of this kind are known per se and in most cases driving studs for the conveyance of the patrices or the like were secured on the conveyer chains, disposed on both sides of the restoring rail, in horizontal disposithe restoring rail. The conveyer chain according to this invention is composed of individual link elements which are guided on both sides of the restoring rail so as to adjoin the same closely and the sides .of the elements facing the patrices or the like 5, are prevented from performing longed to form are formed as driving members to guide upper ears of equal thickness on all the patrices in an aperture of the chain elements in interfitting manner and thus particularly the thick patrices tilting movements or assuming oblique positions during the conveyance. The individual link elements of the conveyer chain are each provided with notches of a width equal to the body parts of the patrices 30, and into which the patrices fit while being conveyed whereby the patrices are kept steady and the tilting is avoided. The parts interconnecting the two conveyer chains situated on either side of the restoring rail slide, in contradistinction to the hitherto known constructions, on the restoring rail whereby sagging of the chain is avoided.

In the accompanying drawing a constructional form of the conveyer chain according to the invention is illustrated by way of example only in connection with a type setting machine, in which Fig. l is an elevational View of a chain element,

Figs. 2 and 3 each show a side elevation of an inner and an outer chain element respectively,

Fig. 4 shows an elevation of the chain, and

Fig. 5 shows a cross section on the line 0-1) in Fig. 4. on a larger scale.

Referring to the drawing, 1 and 2 designate elements of the chain which are provided with apertures lb and 2b for the reception of the patrices, circulating through the machine and provided with the usual serrated control portions. These apertures are of a narrow width to correspond to the thickness of the body of the patrices and the rearward sides of the apertures are profinger shaped driving members 111 & Maschinenfabrik,

and 2a. The outer chain elements 2 are interconnected by rivet bolts 3 on which spacer sleeves 4 are slid to be readily rotatable thereon. These bolts connect the inner chain elements 1 situated at the sides of the restoring rail 5 with each other. This rail is serrated (Fig. 5) to correspond to the mating serrated control portions arranged on the patrices in a manner known per se and secured to the machine frame above the magazine (not shown) into which the patrices are to be restored.

On a shaft 6 mounted in the machine frame at the front end of the distributing or restoring device for dividing the patrices to be restored to the respective channels of the magazine, a chain wheel '7 is arranged. The Wheel 7 drives the conveyer chain in the direction indicated in Fig. 4 along the magazine underneath, in such a manner, that each patrice 8 arriving on its way back to the magazine at the chain loop slung about this wheel is gripped by one of the driving fingers la and 1b and pushed along the restoring rail 5 with the mating serrations on the rail and the patrice interengaging, into the respective channel of the magazine. The patrice 8 is brought on to the chain in such a disposition that the upper ears provided on the carrier plate of each patrice engage into the apertures lb, 21) respectively, thus being secured in position on the chain while being conveyed thereby to the channel of the magazine into which they are to be delivered. The connection bolts 3 slide with the spacer sleeves 4 enclosing the same on the restoring rail 5, whereas the chain elements 1 and 2 are moved with their driving fingers la and 2a past the sides of the restoring rail 5 in close proximity thereto.

I do not limit myself to the particular size, shape, number or arrangement of parts as shown and described, all of which may be varied without going beyond the scope of my invention as shown, described and claimed.

What I claim is:

1. In a conveyer chain for restoring circulating type carrying patrices having restoring dentures in type setting and printing machines, in combination, a restoring rail along which the patrices are moved secured to the machine frame, a conveyer chain cooperating with said rail for moving the patrices along the rail, said chain having link elements provided with notches the thickness of the patrices, said notches receiving the patrices, said elements having extensions adjacent said notches forming downwardly extending abutment arms to engage the patrices.

2. In a conveyer chain for restoring circulat- BBQ ing type carrying patrices having retaining dentures in type setting and printing machines, in combination, a restoring rail along which the patrices are moved secured to the machine frame, a conveyer chain situated above said restoring rail and cooperating with the same for moving the patrices along the same, component link elements in said conveyer chain having notches of' a width equal to the width of the patrices and downwardly extending abutment arms adjacent said notches and extending adjacent the sides of said rail and cooperating with the notches of the elements for steadily holding the same during its conveyance along said rail.

the rail.
